Cataract Surgery in the Hypotonous Eye

摘要: One general etiology of hypotony involves inadequate aqueous humor production by the ciliary body. Inadequate is usually considered after structural processes have been ruled out. Such cases include iridocyclitis, ocular ischemia, traction body detachment, suppressants; chemical toxicity from antimetabolites, laser or cryo-cyclodestruction; systemic hypertonicity, acidosis.2–4 Iridocyclitis a known hypotony. Inflammation increases permeability blood-aqueous barrier, which decreases and disrupts transport epithelium.5,6 This in turn leads to edema. A self-perpetuating cycle may develop as low IOP increase choroidal effusions contribute development ciliochoroidal detachment associated with IOP.7 In advanced inflammation, vasculitis result diminished blood flow further decrease humor.
